2010 Marin Bridgeway Metro quality
 

I found this bike for 120.Are these any good?The front fork is good for a shoulder injury and the rack and fenders are perfect for my commute.But I don't want to waste money on a pos. Thanks for any advice.

I'm not familiar with that particular model, but looking at the specs I don't see any reason to think it's worse than any other bike with entry level components. Marin is generally a reputable brand, but that mainly means that there frames are built in a decent factory overseas and that their component selection is appropriate for the price of the bikes.
